2.2 Metering unit
2.2.1 Polyol/ Cyclopentane metering unit
1 set High precision metering device installed on the frame with adjustable cushion, mainly consist of the following parts:
. 1 Riot motor, Motor safety grade IP54, Taiwan inverter control
. 1 German high pressure metering pump Germany A2VK
. 1 set pressure control device,consist of range 0-1MPa pressure gage and riot pressure switch. To prevent pump fit, set to control pressure: 0.1MPa, when the pressure is lower than the set value,the control system alarm prompt

.1 set high pressure control device,consist of range 0-40MPa pressure gage and riot pressure switch,used to adjust of work pressure of control components, set the working pressure range in 6-22MPa,when pressure beyond this range, equipment downtime alarm and show fault message of work pressure is too low or work pressure is too high
. Ultimate safety pressure of component metering pump set to 25MPa by the relief valve, the relief valve has a mechanical protection function, ensure the use of metering pump and system security
2.2.2 ISO metering unit
Using digital display type pressure gauge control precompression and working pressure of components, drive by ordinary motor driver with same power
2.3 High and low pressure circulation switching unit
High and low pressure circulation switching unit can make components circul low energy consumption.
2.4 Streamline filter
Used to filter components, by turning the handwheel or handle of filter, disposal from the bottom of the filter ball valve.
2.5 Mixing head
High-pressure mixing head using the clean design and high-pressure collision principle, mixing quality mixing head normally associated with material characteristics (viscosity, temperature, density, etc.), injection pressure and injection pressure difference in size. To achieve good mixing effect (flow state for turbulent state), Reynolds number RE must be greater than a critical value, the size of the critical Reynolds number related to the mixing head nozzle form and material system.
2.6 The HL type mixing head is mainly used in the rigid foam production and the opening mould casting

Functions and features:

Main parts of the machine such as metering pump, high pressure mixing head, programmable controllers, high-pressure pipe components, cyclopentane gas sensor probe and the control channel card etc are using imported parts, ensure and improve system reliability.
Equipment metering unit metering pump and motor are connected by magnetic coupling, thus avoid pump shaft leak and extend pump life, enhance system security, reliability; using a large insurance factor design make sure long service life.

Safety precautions:


Installation of protective isolation room and exhaust devices;
Installation of cyclopentane gas monitoring alarm system;
Nitrogen protection;
Explosion-proof electrical appliances;
Equipment grounding;
Anti-leakage control;
Before mixing head pouring, filling nitrogen to displace the air in the cavity;
Remote monitoring system.
